Step‑by‑Step Instructions for Dill Red Onion Dressing
Step 1: Prepare the Vegetables
Start by finely mincing the medium red onion and one clove of garlic. Aim for small, even pieces to ensure a well-distributed flavor throughout your Dill Red Onion Dressing. This process will only take about 3-5 minutes, and the vibrant colors and sharp aromas will inspire your taste buds as you work.
Step 2: Combine Ingredients in a Jar
In a small mason jar, gather your freshly minced onion and garlic, then add the coconut sugar, dried dill, olive oil, white vinegar, and a pinch of sea salt and black pepper. This all-in-one jar method not only simplifies cleanup but also allows the flavors to mingle beautifully.
Step 3: Shake It Up
Secure the lid tightly on the mason jar and shake vigorously for at least 30 seconds. This will help emulsify the olive oil and vinegar, creating a harmonious blend of flavors in your Dill Red Onion Dressing. Watch as the ingredients transform and combine into a luscious dressing.
Step 4: Let It Sit
Allow the dressing to sit for about 5-10 minutes after shaking. This brief resting period lets the flavors meld together beautifully, intensifying the taste of your dressing. You’ll notice the vibrant colors will deepen, promising a delightful addition to your salads.
Step 5: Serve and Store
When ready to use, give the dressing another little shake to mix any settled ingredients. Drizzle it over your favorite salads, or use it as a marinade for vegetables. If you have leftovers, store the dressing in the fridge for up to two weeks in the same mason jar—just remember to shake it well before serving!

Expert Tips for Dill Red Onion Dressing
-
Perfect Mince: Finely mince your red onion and garlic for a better flavor distribution in your Dill Red Onion Dressing; a coarse chop can lead to overpowering bites.
-
Herb Freshness: If using fresh dill, double the quantity for an intense herbal flavor; the dressing benefits from a fresh herbaceous kick!
-
Oil Quality: Always opt for high-quality, dark glass bottled olive oil; it preserves flavor and nutrients better than standard bottles exposed to light.
-
Flavor Infusion: For a richer taste, infuse your olive oil with herbs or spices ahead of time; this simple trick elevates your homemade dressing.
-
Storage Reminder: Store your dressing in the fridge for up to two weeks, but remember to shake it well before each use to re-emulsify the ingredients.
-
Taste Adjustment: Don’t hesitate to adjust the sweetness; add a touch more coconut sugar or substitute with honey based on your personal preference for the perfect balance.
How to Store and Freeze Dill Red Onion Dressing
Fridge: Store your Dill Red Onion Dressing in a tightly sealed mason jar in the fridge for up to two weeks. Give it a good shake before serving to re-emulsify the ingredients.
Room Temperature: Avoid leaving the dressing out at room temperature for more than 2 hours. Always refrigerate once made to maintain maximum freshness and flavor.
Freezer: For longer storage, consider freezing the dressing in an ice cube tray. Once frozen, transfer the cubes to an airtight bag for up to 2 months. Thaw as needed!
Reheating: While this dressing is best served chilled, thaw any frozen cubes overnight in the fridge before using for salads or marinades. Enjoy the fresh taste!
Make Ahead Options
Preparing your Dill Red Onion Dressing ahead of time is a game changer for busy weeknights! You can mince the red onion and garlic up to 24 hours in advance, storing them in an airtight container in the refrigerator to preserve freshness and prevent browning. Additionally, you can measure out the dry ingredients—coconut sugar, dried dill, sea salt, and pepper—in a separate container. When it’s time to enjoy your dressing, simply combine the prepped ingredients in a mason jar with the olive oil and white vinegar, shake well, and let it sit for about 5-10 minutes for flavors to meld. This way, you’ll have a vibrant, homemade dressing on hand with minimal effort, just as delicious as when freshly made!

Dill Red Onion Salad Dressing Recipe FAQs
How do I choose a ripe red onion?
Absolutely! When selecting a medium red onion, look for one that is firm and smooth, without any dark spots or soft patches. A good onion should feel heavy for its size, indicating moisture and freshness. If you notice any sprouting, it’s best to avoid using it, as flavor and crunch may diminish.
How long does the dressing last in the fridge?
Great question! You can store your Dill Red Onion Dressing in a tightly sealed mason jar in the refrigerator for up to two weeks. Just remember to give it a good shake before using, as the ingredients may separate while stored.
Can I freeze this dressing?
Very! To freeze your Dill Red Onion Dressing, simply pour it into an ice cube tray. Once the dressing is fully frozen (about 2-3 hours), transfer the cubes into a resealable plastic bag. This way, you can keep them in the freezer for up to 2 months. When you’re ready to use them, just thaw overnight in the fridge!
What should I do if the dressing is too salty?
No worries at all! If you find your Dill Red Onion Dressing is a bit too salty for your taste, you can balance it out by adding a little more olive oil or vinegar to dilute the saltiness. Alternatively, adding a bit of coconut sugar can help to neutralize the salt flavor as well—just start with a small amount and adjust to your liking.
Is this dressing suitable for people with allergies?
Absolutely! This dressing is not only vegan but can also cater to various dietary restrictions. However, it does contain onions and garlic, which may trigger certain allergies. Always check ingredient labels for any substitutions you might make, like honey instead of coconut sugar, to ensure it’s safe for everyone enjoying it.
Can I use fresh dill instead of dried?
You bet! If you prefer the vibrant flavor of fresh dill, simply double the amount called for in the recipe. Fresh dill gives your dressing an even brighter, fresher taste that can be absolutely delightful, especially during the spring and summer months when herbs are at their peak!
